⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through arbitrary code execution with user privileges, potentially leading to data theft, ransomware deployment, or persistent backdoor installation.
Likely Case
Local privilege escalation leading to malware installation, credential theft, or lateral movement within the network.
If Mitigated
Limited impact if proper application whitelisting and least privilege principles are enforced, restricting unauthorized DLL execution.
🎯 Exploit Status
Exploitation requires local access to place malicious DLL in a location where the installer will execute it with improper permissions.
